Note about port addressing modes
There is a distinction between Group G and Group H functionality
regarding port addressing modes.
Group G and earlier
Standard address mode (0-15) can be any of the following:
•
DPNSS1 (DDSL)
•
DASS2 (DDSL)
•
APNSS (LSSL)
•
Q.931 (DCHI)
•
ISL (DCHI)
•
SDI
•
ESDI
Expanded address mode (0-159) can be either of the following:
•
DPNSS1 (DDSL)
•
DASS2 (DDSL)
The expanded mode addressing has no impact on the standard mode
addressing; that is, DASS2 D-channel (DDSL) 7 in the expanded mode
can exist with the Q.931 D-channel (DCHI) 7 in the standard mode.
Theoretically, it is possible to have 160 DASS2 D-channels and 16 other
I/O devices. In practise, however, there is a limit of 40 addresses in
expanded mode and 16 in standard mode, for a total of 56 addresses.
Action
Configure the DASS2 D-channel port number, which
is a logical port number independent of the actual I/O
port address. This is the number used to reference
the D-channel in LD 74; the value is entered against
the ADAN prompt, and is in the range of 0-63.
Define clock synchronization control.
Define the data blocks used for the DASS2 protocols.
Define a DASS2 customer.
Create the service routes to be used.
Create the channels within the service routes.
Bring the DASS2 link into service.
